Terminology

What is Scanning?

Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The UBC785XLT scans the Frequencies you have programmed into the Scanner’s channels you program until it finds an active frequency.

Scanning stops on an active frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until another transmission is received.

What is Searching?

The UBC785XLT can search each of its 22 bands to find active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into your Scanner’s channels. The scanner automatically chooses between two speeds while searching. Turbo Search can search the VHF FM bands at up to 300 steps per second (while 5 kHz only).

Setup

Connecting an Antenna

You must install an antenna before you can operate the scanner. You have been provided a standard telescopic antenna that works well with this scanner, but you may want to purchases another type to increase the range. To connect the telescopic antenna, simply connect it to the BNC type ANT. connector on the rear of the scanner. You can purchase a variety of scanner antennas for both mobile and base station available at a local electronics store. Choose the one that best meets your needs.

When deciding on a mobile or base station antenna and its location, consider these points.

• The antenna should be as high as possible on a vehicle or a house.

• The antenna and its cable should be as far as possible from sources of electrical noise

(ignition systems, gauges, and so on).

• The antenna should be vertical for the best performance.

Mounting an Antenna

Once you choose an antenna, follow the mounting instructions supplied with the antenna. Then route the antenna cable to the scanner.

The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such as an external mobile antenna or an outdoor base station antenna.

Always use 50 ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable If your antenna’s cable does not have a BNC connector, you will also need a BNC adapter (available at a local electronics store).

Follow the Installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the

ANT. jack.

Warning: Use extreme caution when you install or remove an outdoor antenna. If the

antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. DO NOT attempt to do it yourself.

Optional Antenna

If you have chosen an optional mobile antenna, connect the antenna plug into the ANT. connector on the rear of the scanner. (For more information on antenna installation, please refer to the instruction guide that came with your antenna.)

Typical Mounting Methods

The UBC785XLT can be conveniently mounted on a table, bulkhead, overhead, or any other desired location (refer to figure below for typical mounting methods).

Caution: Make sure there are no hidden electrical wires or other items behind the desired

location before proceeding. Check that free access for mounting and cabling is available.

Mounting the Scanner in Your Vehicle

Before you mount the scanner, make sure you have all the necessary materials. Then confirm that the scanner fits your vehicle’s mounting area. This unit requires a mounting area of 2-3/8 inch high by 6-15/16 inch wide by 6-9/16 inch deep (61 x 176.5 x 167 mm).

Caution: Be sure to avoid obstructions behind the mounting surface.

Follow these steps to mount the scanner in your vehicle.

1. Choose a mounting location, then use the supplied mounting bracket as a template to mark the positions for the mounting screw holes.

2. In the marked positions, drill holes slightly smaller than the supplied screws.

3. Attach the mounting bracket to the mounting location using the supplied screws and lock washers.

4. Attach the scanner to the mounting bracket using the supplied mounting knobs.

5. Connect the antenna’s cable to the

ANT. connector

on the back of the scanner.

Note: If the antenna cable’s connector does not fit in the ANT.

connector, you might also need a Motorola-to BNC antenna plug adapter (available at a local electronics store).

Applying Power for Vehicle Installation

You can power your scanner using either the supplied DC power cord or your vehicle’s cigarette lighter socket using DC cigarette lighter power cord.

Caution: You must use a power source that supplies 13.8 V DC and delivers at least

700 mA. Your standard 12 V car battery should be sufficient. The cord connector’s center tip must be set to positive and its plug must fit the scanner’s DC 13.8 V jack. The supplied DC power cord meets these specifications. Using a power cord that does not meet these specifications could damage the scanner or the adapter.

• Always connect the adapter or DC power cord to the scanner before you connect it to the power source. When you finish, disconnect the adapter or DC power cord from the power source before you disconnect it from the scanner.

• For added safety and to protect your scanner, disconnect the cable from your vehicle battery’s negative (-) terminal before you begin.

Follow these steps to connect the supplied DC power cord.

1. Connect the power cord’s black wire to a chassis ground, such as a metal screw attached to a metal part of the vehicle’s frame. Be sure that the screw is not insulated from the frame by a plastic part.

2. Connect the power cord’s red wire (with in-line fuse) to a source of voltage that turns on and off with the ignition switch, such as a spare accessory terminal in your vehicle’s fuse box.

3. Insert the power cord’s barrel plug into the

DC 13.8 V jack

on the back of the scanner.

4. Reconnect the cable to the vehicle battery’s negative (-) terminal.

To power the scanner from a vehicle’s 12 V power source (such as a cigarette-lighter socket), you need a cigarette-lighter adapter.

To connect an optional DC cigarette-lighter power cable, insert its barrel plug into the DC 13.8 V jack on the back of the scanner, then plug the power cable into your vehicle’s cigarette lighter socket.

Note: If you use a cigarette-lighter power cable and your vehicle’s engine is running, you

might hear electrical noise from the engine while scanning. This is normal.

Desktop Installation

You can place this scanner on a desk, shelf, or table to use it as a base station.

1. Flip up the feet for desk installation.

2. Extend the antenna to full vertical position. Adjust the angle for best reception.

Applying Power Using Standard AC Power

To power the scanner from an AC outlet, use the provided AC adapter with a 5.5 mm outer diameter/2.1mm inner diameter tip.

Caution: You must use a Class 2 power source that supplies 13.8 V DC and delivers at

least 700 mA. The cord connector’s center tip must be set to positive and its plug must fit the scanner’s

DC 13.8 V jack. Using an adapter that does not meet these

specifications could damage the scanner or the adapter.

• Always connect the AC adapter to the scanner before you connect it to AC power. When you finish, disconnect the adapter from the AC power before you disconnect it from the scanner.

1. Insert the adapter’s barrel plug into the

13.8 V

jack on the back of the scanner.

2. Plug the adapter into a standard AC outlet.

Note: Use only the AC adapter supplied with

your scanner.

Connecting an External Speaker

In a noisy area, an external speaker (available at a local electronics store) positioned in the right place might provide more comfortable listening.

Plug the speaker cable’s 1/8 inch (3.5 mm) plug into your scanner’s

EXT. SP. jack.

Note: Connecting an external speaker

disconnects the scanner’s internal speaker.

Connecting an Earphone

For private listening, you can connect an earphone with a 1/8 inch (3.5 mm) plug to the

EXT. SP. jack on the back of the scanner. Be very careful as damage to your hearing can result if the VOL control is not set to the lowest level first.

See below for "Listening Safely" instructions. (Your local electronics store should carry a wide selection of earphones.) Once the earphone is connected, it will automatically disconnects the internal speaker.

13.8V

Page 21

Listening Safely

To protect your hearing, follow these guidelines when you use an earphone or headphones.

• Do not listen at extremely high volume levels. Extended high volume listening can lead to permanent hearing loss.

• Set the

VOL to the lowest setting before you begin listening. After you begin listening,

adjust the

VOL to a comfortable level.

• Once you set the

VOL, do not increase it. Over time, your ears adapt to the volume level,

so a volume level that does not cause discomfort might still damage your hearing.

Connecting the Clone Cable

You can transfer the programmed data to and from another UBC785XLT scanner using a RS232C Cable (9 pin to 9 pin) (not supplied). Connect the cable between each scanner’s REMOTE jacks. See "Clone Mode" on page 41. You can also upload or download the programmed data to or from a PC using an optional PC interface kit available through your local electronics store.

Connecting the Tape Recorder

You can use a standard tape recorder or a VOX (Voice Operated Control) recorder. To connect the recorder to the scanner, connect a cable with a 1/8 inch (3.5 mm) plug from the tape recorder’s remote jack to the

TAPE OUT jack on the back of the scanner. (Your local electronics store should carry a wide selection of cables and tape recorders.) Refer to the "Record" section under "Additional Features" in the manual.

Remember!

• You must mark a channel, ID, talkgroup, or bank for Recording in order for this feature to work.

• This feature does not work if your scanner is set with

MUTE ON.

Basic Operation

Turn the Scanner On

Turn the VOL control clockwise out of the detent position. The scanner automatically starts scanning. Since there are no frequencies programmed in your scanner initially, you may not receive any signals. Once you set the squelch and program some frequencies, you will be hearing conversations regularly.

Setting the Squelch

To set the squelch, you must be in the hold mode, and you should not be receiving a signal on your scanner.

1. Press

▲/HOLD until you do not hear a signal.

2. Make sure that the

VOL is set to a comfortable

listening level.

3. Think of the Squelch Control as a gate. Turn the

SQUELCH control fully counter-clockwise. This raises the "Squelch Gate" so high that only very strong signals can get through.

4. Turn

SQUELCH clockwise until you hear a hiss. This lowers the "Squelch Gate" so that everything gets through – noise, weak signals, medium signals and strong signals.

5. Turn

SQUELCH back counter-clockwise just until the hiss stops.

Now the "Squelch Gate" allows only clear signals through.

Next you must program some frequencies (page 24). It is recommended that you read the next part "Understanding the Menu System" because it will assist you in accessing and understanding many of the features. Later in a section called "Additional Features", you will find explanations on how to disable the keypad acknowledgement tones, to mute the audio, to change the appearance of the display and other general features.

Understanding the Menu System

It is very important for you to understand the Menu screen. To navigate through the Menu screen is really quite simple. Many of the features of this scanner, can only be accessed by the Menu screens. There are several ways to get through the screens. First of all, press MENU to get started. Anytime you want to exit this mode or simply quit from where you are, repeatedly press

MENU until the scanner returns to the original state or you can press

SCAN or SRCH to exit directly MENU MODE. Anytime you are in the Menu mode, the audio

will be muted.

To assist you in understanding the Menu screen, flow charts are provided towards the back of the manual so you can follow along. Two things to remember are

rotate the through the

menu and press

E or VFO to execute the command. For simplicity, we have chosen to

rotate the

VFO control up or down in order to scroll through the menu and the E key for

entering or executing a command. Once you have pressed the E key and executed the final

choice (for instance,

ON or OFF), the display backs up to the previous level of options.

Also direct entry of the numbers in the flow chart will get you through the screens, but the other screen options are not visible. This method should be used only after you have gone through the manual at least once. Tearout shortcut cards (see pages 4 and 5) are provided to assist you in the direct entry method for commonly used features.

The illustration below shows the first level of the Menu screen. These levels are then provided in a flow chart on pages 52 to 54. You will find a description section to explain the meanings of these functions on the next pages. Then, you will be walked through all the steps of programming, scanning and searching.

☞Hint: You can check the options you programmed on the display when you press and

hold

MENU for 2 seconds in the following modes.

• Scan mode/Scan Hold mode.

• Chain Search mode/Chain Search Hold mode

Menu Description and Numeric Keypad Equivalents

Below are the Menu screens and a brief description or purpose of the feature.

1:SEARCH OPTION

1:AIR STEP

You can select the air band step 12.5kHz or 8.33 kHz.

2:CHAIN SEARCH

1:CHAIN SEARCH

You need to turn Chain Search feature to ON if you use the Chain Search feature.

2:SEARCH RANGE

You can program up to 10 search ranges. The first time you program a range you will need to do so through the Menu. After the first time you can program a range as you do on most any other scanner, using the numeric keypad,

▲,

▼ and VFO control. Use this Menu item to select the search range that you

want to program. You can program range 1 through 10, one at a time. For each of the ranges, the following options can be modified.

1:RANGE

Enter the upper and lower frequency limits of the Search Range.

2:STEPS

You can assign a variety of step sizes to the search range. Note: The default step is usually acceptable and is listed on page XX.

3:MODE

You can change the Auto receive mode to AM, FM, WFM and NFM.

4:ALPHA TAG

You can name to each channels and banks with up to 16 charactors.

3:DELAY

Set the delay for the search ranges. This applies to all the ranges (See

CHANNEL DATA-STEPS).

4:ATTENUATOR

If you are near an signal source which emits unusually strong signal, the scanner may be overloaded with its signal. Once overloaded, the scanner may keep stopping on that signal and miss other transmissions. UBC785XLT comes with an RF Attenuation feature. It attenuates (reduces) the strength of a incoming signal in all modes to prevent stronger signals from overloading the scanner.

5:TONE DATA

The default mode is OFF. This means that you will receive all transmissions on any frequencies that are active within your search range(s). By selecting CTCSS (analog) or DCS(digital) subaudible tone you can set the radio to receive only a particular subaudible tone to be received during your search. You can also lockout a particular subaudible tone. You may wish to do this if you want to search a range but not hear transmissions on any frequency that has a particular subaudible tone.

UB343ZH_UBC785XLT_OM_0622 6/22/06 3:01 PM Page 20

Page 25

Note: Through the System Menu you can set the radio to operate in Tone

Search mode during Search as well. In this mode, the radio will automatically determine the active subaudible tone on any frequency received during the search.

6:RECORD

With this feature set to on, any frequency that is active during the search, can be recorded to an external tape recorder.

7:AUTO STORE

You can automatically store the active frequencies found during a search into the memory. You can select the bank to program. The audio will be muted.

2:SCAN OPTION

1:FREQUENCY

Allows you to program a frequency to a memory channel or edit the frequencyl already programmed. You can also set an alphanumeric text tag (alpha tag) for each programmed frequencies.

2:DELAY

You can set delay for the memory channel. The default delay is two seconds.

3:TONE DATA

You can set a CTCSS (analog) or DCS (digital) subaudible tone for a frequency. To do so you must have the SQ Mode in the System Menu set to Tone SQ. You can also program a subaudible tone easily by pressing the

E key in Scan Hold mode after programming a frequency. This will bring up the Tone Data menu without having to navigate the Menu. By doing this you will receive all transmissions on the frequency, regardless of the subaudible tone, except the one which you have locked. Any transmissions with that tone will not be received.

4:BEEP ALERT

You can set a Beep Alert per channel to alert you when specific frequencies are active. For example, you may wish to be alerted anytime a mutual aid fire frequency is active. With Beep Alert, you will hear three beeps at the start of each transmission that you have flagged as such. You will also notice that as you scroll pass the flagged channel(s), you will hear three beeps.

5:ATTENUATOR See 1: SEARCH OPTION/ 2:CHAIN SERACH/ 4:ATTENUATOR.

6:STEPS

Your UBCD785D is programmed with default step sizes for each frequency range (see page 1). Steps are important if you are interested in using the

VFO to tune off from a frequency programmed into memory or if you wish to program a frequency that the default step size will not accept.

7:MODE

Default Auto receive modes are also programmed into memory. AM for aircraft for example. You can change the default settings on a per-channel basis with this Menu item.

UB343ZH_UBC785XLT_OM_0622 6/22/06 3:01 PM Page 21

Page 26

8:RECORD

You can flag any channel for recording using this menu function. Use your own recording device plugged into the jack on the back of the scanner.

3:SYSTEM OPTION

1:DIMMER

Allows you to change the brightness of the display.

2:SCREEN MASK

Screen Mask allows you to limit what appears on the display to the alpha tags that you have set for a channel along with a few function icons. Screen Mask removes the frequency, receiving mode tone data and signal strength bars. This mode is particularly useful in public safety vehicles where "information overload" is already a problem. Screen Mask does not work in Search mode.

3:KEY BEEP

Use this function to turn OFF the keypad acknowledgement beep. The default setting is

ON.

4:ENTER LOCK

Use Enter Lock to prevent accidental re-programming of channels, tone (CTCSS/DCS) and talk groups entered into memory. The default setting is

OFF.

5:PC CONTROL

Use this function to set the transfer speed (baud rate) at which your personal computer (PC) communicates with the scanner when downloading information into your scanner using Uniden E-Scanner software. See page 40 for details.

6:CLONE

You can clone all the programming, including frequencies and alpha tags as well as bank settings and other parameters from another UBC785XLT.

7:DATA SKIP

A scanner will normally stop on any transmission it receives. This means the UBCD785D will occasionally stop on data signals and unmodulated transmissions. You can automatically skip many of these types of transmissions during search.

8:SQ MODE

The SQ Mode allows you to set at your option, whether the scanner will stop on all active transmissions on a particular frequency or it will only respond to transmissions with a pre-set subaudible tone. This applies to both Conventional Search and Scan modes. The options are as follows:

UB343ZH_UBC785XLT_OM_0622 6/22/06 3:01 PM Page 22

Page 27

1. CSQ - The default setting is CSQ (carrier squelch). In this mode the scanner will stop on any transmission on a programmed frequency.

2. TONE SQ - In Tone Squelch mode, if you have set a subaudible tone for a frequency, the scanner will only stop on that frequency if the transmission includes the prescribed tone.

3. TONE SEARCH - In this mode, as soon as the scanner stops on any channel, the scanner will begin to search for any subaudible tone that is being used on a transmitted frequency. The scanner will check each CTCSS tone sequentially and it will find DCS tones instantly.

9:BANK TAG

Allows you to set an alphanumeric text tag for individual banks in the scanner (1-10). (The "0" key represents Bank number 10.) For example, you may wish to set the Bank one text tag as Law Enforcement, the second bank as Fire, etc.

Programming Tips

• Group similar services into a bank. For example, program police frequencies in channels 1 through 10 and fire/emergency into channels 51 through 60, and so on.

• Put the frequency that you listen to the most or the most important frequency into a Priority channel.

• To quickly program a series of channels, start with the lowest number channel.

For example, when you are programming five new frequencies into channels 4 through 8, start with channel 4. After you finish programming a channel, rotate the

VFO up or

press

▲ to go to the next higher channel.

• Write down your programmed channels and frequencies and put them in a convenient place in case of accidental reprogramming.

• Frequencies are rounded off according to the step of each channel.

• When you are overwriting a tagged channel with a new frequency, the previous alpha tag

will be deleted. Re-register the alpha tag.

• When programming frequencies, a 2 second delay is set automatically but can be changed in the menu mode.

Care and Maintenance

General Use

• Turn the scanner OFF before disconnecting the power.

• Always write down the programmed frequencies in the event of memory loss.

• If memory is lost, simply reprogram each channel.

The display shows 000.0000 in all channels when there has been a memory loss.

• Always press each button firmly until you hear the entry tone for that key entry, unless you have turned

2:OFF the

3:KEY BEEP in the menu system.

Location

• Do not use the scanner in high-moisture environments such as the kitchen or bathroom.

• Avoid placing the unit in direct sunlight or near heating

elements or vents.

• If the scanner receives strong interference or electrical noise, move it or its antenna away from the source of the noise. If possible, a higher elevation, may provide better reception.

Cleaning

• Disconnect the power to the unit before cleaning.

• Clean the outside of the scanner with a mild detergent.

To prevent scratches, do not use abrasive cleaners or solvents. Be careful not to rub the LCD window.

• Do not use excessive amounts of water.

Repairs

• Do not attempt any repair. The scanner contains no user serviceable parts. Contact the Uniden Customer Service Center or take it to a qualified repair technician.

Birdies

• All radios can receive birdies (undesired signals). If your scanner stops during Scan mode and no sound is heard, it may be receiving a birdie. Birdies are internally generated signals inherent in the electronics of the receiver.

Press

L/O to lockout the channel, and then press RSM to resume scanning.

Troubleshooting

If your UBC785XLT is not performing properly, try the following steps.

Resetting the Scanner

If the scanner's display locks up or stops operating properly, you might need to reset the scanner.

Caution: This procedure clears all the information (except the band plan data) you have

stored in the scanner. Before you reset the scanner, try turning it off and on to see if it begins working properly. Reset the scanner only when you are sure it is not working properly.

1. Turn off the scanner.

2. While holding down 2, 9, and Hold

▲, turn on the scanner. It takes about 15 seconds to

initialize and

Glossary of Terms

Alpha tag - This term refers to an alphanumeric text tag that you can enter to describe the

individual frequencies that you have programmed. Rather than having to associate a specific frequency to the individuals that are using it, you can enter the actual name of the group. This will eliminate the need for memorizing the group’s frequency.

Attenuator - This scanner comes with a feature to attenuate or reduce the signal strength.

The built-in attenuator can be turned on specific frequencies to prevent strong signals from overloading the scanner input, possibly damaging the scanner or missing other transmissions due to the repeated stopping on the stronger signal.

Clone - This term identifies the ability to set up a duplicate scanner. This function allows

you to clone all the programming information, including frequencies, talkgroups and alpha tags as well as bank settings and other parameters from one UBC785XLT to another or UBC785XLT.

CTCSS - (Continuous Tone Controlled Squelch System) refers to a system where the radio

receivers are equipped with tone responsive devices which allow audio signals to appear at the audio output, select voice processing such as scrambling or control repeater functions only when a carrier modulated with a specific tone is received. This method may be used to restrict access to the repeater or receiver, or reduce interference where several stations with output frequencies in close proximity of each other make it difficult to hear the conversation you are interested in. With CTCSS squelching, you can eliminate the possibility of hearing unwanted conversations by selecting one of the 38 standard subaudible tones. You will only hear those transmissions that have been programmed on specific frequencies with the specific subaudible tone that you have selected.

DCS - (Digital Controlled Squelch) refers to a system where the radio receivers are

equipped with data burst responsive devices which allow audio signals to appear at the audio output, select voice processing such as scrambling or control repeater functions only when a carrier modulated with specific data burst is received. This method may be used to restrict access to the repeater or receiver, or reduce interference where several stations with output frequencies in close proximity of each other make it difficult to hear the conversation you are interested in. With DCS squelching, you can eliminate the possibility of hearing unwanted conversations by selecting one of the 104 standard data burst subaudible tones. You will only hear those transmissions that have been programmed on specific frequencies with the specific subaudible tone that you have selected.

Enter Lock - This is the term used for locking the keypad. This prevents accidental

re-programming of channels and talkgroups entered into memory. The default setting is OFF.

When ENTER LOCK is enabled, the following functions will be disabled:

• Enter or modify the Memory Channel frequency

• Enter or modify the Tone information

UB343ZH_UBC785XLT_OM_0622 6/22/06 3:01 PM Page 49

Page 54

Key Beep - This is another term for the tone you hear as a keypad acknowledgement beep.

The default setting is on. If you have turned the Key Beep off, you now have a silent keypad. You will not hear a tone each time you press a key.

PC Control - This term is associated with the ability to program frequencies and other

useful information via a computer by means of third party software. You can change the transfer speed on the scanner needed to be compatible with your PC. (See page 40)

Screen Mask - Screen Mask reduces the amount of information that appears on the

display. Alpha tags that you have set for a channel along with a few function icons will appear only on the display. This mode is particularly useful in public safety vehicles where that are already overloaded with information. Screen Mask does not work in Search mode.
